As a small episode, the topic of skin color quickly enlivened the atmosphere of the live broadcast room.

After a pause, Bi Fang brought the topic back on track.

"I don't think anyone knows about the content of this live broadcast, right?"

[Know, know, Sahara Sahara!]

】

【Death Desert!】 】

[The great leprosy spot of the earth! 】

As a super desert with an area comparable to the whole of China, the name of the Sahara is known to everyone.

It is like a huge and ugly scar, which stands out on the land of Africa and becomes the famous forbidden area of life.

It is said that only after experiencing the test of life and death on the Sahara Desert will you truly fall in love with the oasis and love life.

Just from the corner of the information revealed in this discourse, you can peek into the cruelty and wildness of this world.

Challenging oneself and understanding the true meaning of life is what Bifang has been doing.

Everyone has been looking forward to this for a long time.

"That's right, before crossing Nemo Point, I made everything very clear, this time the live broadcast is a crossing of Nemo Point plus crossing the Sahara, the overall time limit is 120 days, so strictly speaking, our live broadcast is only a third of the way through."

Bi Fang pointed to the desert and the Gobi in front of him.

"As you can see, there is a desert in front of us, and you guessed it right, Lao Mu and I are located in the northernmost part of Burkina Faso, and this is also the southernmost point of the Sahara Desert."

"I divided the desert into two levels, the first level is similar to the Gobi, although the environment is harsh, there are still people living on the ground, the ground is full of shrubs, and even grass, and the second level, as everyone imagined, is full of sand dunes, a real no man's land."

"Judging from the data, the Sahara is actually a very big concept, almost occupying northern Africa, which is the entire Sahara Desert, but it is surrounded by a large circle of first-level deserts, and only the center is a real no-man's land, that is, a second-level desert."

"Our entry point is in Burkina Faso, and from here we will be able to go directly to the heart of the Sahara."

"The initial route from then on is from Burkina Faso→ Mali→ Algeria→ Niger→ Chad→ Libya → Egypt, across the entire Saharan core, of course, in between."

The Sahara Desert is about 4,800 kilometers long from east to west and 1,300-1,900 kilometers from north to south.

The so-called crossing is naturally from east to west, not from south to north, and if you don't play those who are vain, you have to challenge the most ruthless.

The route chosen by Bi Fang, according to the map, is roughly inserted from the lower left corner of the Sahara, then reaches the center line, and then crosses the entire east and west, with a length of more than 5,000 kilometers.

"But we only have eighty days left, and time is too short, so my plan is to catch a camel before we set off."

[666, Fang Shen's shot, it will be extraordinary! ] 】

[I remember that Lao Fang didn't say that there are very few camels, they are all protected animals, and this thing is said to be caught? 】

[Cool, just after watching Nemo Point, I will have a Sahara, is this happiness? 】

"This brings us to the conceptual question, and Mugallen asked me the same question just now, so I felt the need to do a simple science popularization."

"Wild camels, wild camels, domestic camels, these are actually three things, the first is a protected animal, the number is indeed scarce, but the latter two are not ......."

With Bi Fang's explanation, the audience in front of the screen gradually had a clear concept.

Wild camels and domestic camels, if not for the absence of reproductive isolation, can even be said to be two species.

Because of the genetic difference between the two, the difference even reaches 3%, which is 00.5%~1.4% higher than the genetic difference between humans and gorillas!

It is true that domestic camels become wild when they escape, but they cannot be said to be wild camels, and the two have diverged into two different species only 800,000 years ago.

However, the so-called genetic difference is greater than that between humans and chimpanzees, which can indicate that the two have been differentiated for a long time, but it cannot be considered that the relationship between it and domestic camels is farther than that between humans and chimpanzees, because the statistical caliber is different.

There is reproductive isolation between humans and chimpanzees, while there is no barrier between domestic camels and wild camels.

In areas where wild camels are available, domestic camels are not allowed to be reared in order to prevent genetic contamination of wild camel populations by domestic camels.

Wild camels are scarce and protected, and Bi Fang has no idea about it.

But the wild camel, Bi Fang not only has, but also has a lot of ideas!

Wild domestic camels are undoubtedly much easier to tame than wild camels, and are more common in the Sahara Desert, and are not rare creatures at all, and may even number in the hundreds of thousands.

The family camels that have escaped from the environment have multiplied in the desert from generation to generation, and although they are extremely wild, there are still very different things in the genes of wild camels.

Camels have very few natural predators, and they are extremely combative, and once they have the right environment, they can reproduce on a large scale.

Just look at Audilia, where millions of wild camels are overrun.

At first, Bi Fang actually didn't have the idea of catching wild camels, but wanted to buy one directly, or choose the life-saving camel named Naren that he met in the Qaidam Desert, which was a peerless camel that could come back to see you after being strangled.

Camels that have been domesticated, or even touched in person, are undoubtedly the best choice, which can reduce many accidents and shorten the run-in period.

But Bi Fang thought about it, it was too boring to do so.

Anyone can buy camels and pay some money, but how can they be cheeky enough to say that they have crossed the Sahara on their own?

If you want to do it, you have to be thorough and really do it all by yourself.

Since his "debut", Bi Fang has really not used such a large amount of external assistance, and he does not want to be an exception this time.

Compared with so many entanglements that had existed in Bi Fang's heart, the audience was not surprised by Bi Fang's choice, on the contrary, they felt that it was Bi Fang.

That's how a real man should be.

Mugallen, who was a porter, came out to join in the fun and quickly left, and Bi Fang wandered around the semi-desert area alone with a backpack.

"Camels are called the ships of the desert because they are hard-working, and there is a lot of fat in the hump, which can be broken down into water and energy, so that they can go without drinking water and eating for a long time, but that doesn't mean they don't need to drink water or food."

"Wild camels are as fearful as humans, so the semi-desert areas are sparsely populated, but with large areas of vegetation are their favorites, and we look for them here, and we should meet them soon."
